Darrin, a foot longer you'll need a steering wheel on top of that a sail to control it. Some may remember the photo posted of the propeller for this beast in Darrin's hand. The photo above shows it really is BIG! I will want to be there! Not necessarily when he launches it but when he tries to recover it from the water. Hydraulic hoist anyone?

Maybe spring loaded doors in the bottom to dump the water as it is lifted up.
